Just wondering if anybody could tell me what the correct syntax is for have 2 numbers in between something.

IF (box2_y1 <= box1_y1 <= box2_y2) THEN colDetected = 1

Right now im trying to do some collision detection and this syntax is producing an automatic collision despite the 2 rectangles being nowhere near each other.

Help much appreciated, thanks.

im sure you can't lay it out like that, try

IF (box2_y1 <= box1_y1 and box1_y1 <= box2_y2) THEN colDetected = 1

or try a nested if ie,

if (box2_y1 <= box1_y1)
if (box1_y1 <= box2_y2) then colDetected = 1
endif
